Filed: 1958-04-16
Abstract: 844,665. Parking meters. BLOCTUBE CONTROLS Ltd. April 16, 1959 [April 16, 1958], No. 12052/58. Class 27 In a modification of the parking meter of Specification 775,509, in which insertion of a correct-sized coin moves a pawl 1 so that it connects with a driving link 2 and loads a spring 3, a notch 11 on the pawl engages with a pin 12 on an arm 13 resiliently mounted on the link but, if an oversize coin is inserted, the pawl moves further upwards to disengage the pin from the notch and, on the return stroke of the pawl under the action of the spring, the pin is guided over the face 14<SP>2</SP> of a cam 14 on the pawl, thus preventing the pin from engaging the notch. The top inner face 141 of the cam is chamfered so that the pin is flexed inwards before it engages the notch 11. The toe 11 of the pawl is arranged, during its further travel, to swing a lever 32 into a position such that it obstructs return of a trigger carrier 30 to rest position on a lug 31 and the oversize coin, which has passed the gate 6 and rests in a shoot 20 adjacent a discharge door, is delivered into a coin box when the discharge door is opened automatically on insertion of a further coin. The lever 32 is held in its two positions by a leaf spring 34 and is returned to rest position by a lug 36 which moves as the gate 6 is being opened and engages a pin 35 on the lever.

Title: Organosilicon moulding compositions
IPC: C08G77/06
Filed: 1962-03-29
Abstract: A homogeneous solution obtained by hydrolysing one or more alkoxysilanes with water in the presence of an organic ortho- or polytitanate, or hydrolysis catalyst (see Division C3) is used, after the addition of conventional curing catalysts, for impregnating fillers as by dipping, spraying, brushing or roller coating. In a modification, the siloxanes are formed in situ by contacting the fillers with a mixture of the silane and titanate and then with water. The fillers (in sheet, fibrous or particulate form) can be asbestos fibres, diatomaceous earth, tale, glass fibres or powder, flake or integrated mica, Al2O3, TiO2, MgO, Fe2O3, ZnO, crushe quartz, various silicas or C black.  The impregnated fillers can then be heated to cure the siloxane and consolidate the filler and can subsequently be moulded.  In Example 26, Al2O3 was dipped into a mixture of phenyltrimethoxysilane, methyltrimethoxysilane and tetraisopropyl titanate, and then dipped into water to form a slurry and the slurry shaped into a disc which was air dried and subsequently moulded under pressure at 150 DEG  C. for 4 hours.ALSO:A homogeneous solution is obtained by mixing (1) one or more silanes of the formula RnSi (OR1)4-n in which each R is a phenyl radical or an alkyl or alkenyl radical of less than 4 C atoms, each R1 is an alkyl group of less than 4 C atoms and n is 0,1,2 or 3 and has an average value of from 0.9 to 1.9, (2) at least 0.5 mole of water per mole of silane [OR1] radicals, and (3) a catalyst which is an orthotitanate of the formula Ti-(OR11)4, or a partial condensate thereof, in which R11 is a hydrocarbon of 1 to 30 C atoms with or without nitrogen or oxygen atoms in certain forms, the catalyst being present in amount to provide 0.0001 to 0.012 atom of Ti per atom of Si.  Numerous examples of hydrolysis catalysts (3) are given.  A curing catalyst can be mixed with the silane, water and titanate to enhance the curing of the hydrolysis product; suitable curing catalysts are those disclosed in Specification 848,373 and metal carboxylates, amines and quaternary ammonium compounds.  The products are used for impregnating fillers, as by dipping, spraying, brushing, or roller coating.  In a modification the siloxanes are formed in situ by contacting the fillers with a mixture of the silane and titanate and then with water.  The fillers, in sheet, fibrous or particulate form, can be metals, asbestos fibres or cloth, diatomaceous earth, talc, glass powder fibres or cloth, flake and integrated mica, Al2O3, TiO2, MgO, Fe2O3, ZnO, crushed quartz, silicas, C black, paper, nylon or polyester fibres.  The impregnated fillers can then be heated and subsequently moulded or formed into laminates. Examples are given.

Title: Printing telegraph apparatus
IPC: H04L13/06
Filed: 1940-08-06
Abstract: 540,994. Type-printing telegraphy. CREED & CO., Ltd. Aug. 6, 1940, No. 12641. Convention date, Oct. 23, 1939. [Class 40 (iii)] A tape transmitter, for controlling receiving printers provided with tabulating mechanism, includes a start-stop distributer which is arrested in its stop position whenever a " tabulating " signal is transmitted, thus allowing time for the movement of the receiver carriage to the tabulating position. The tape-sensing means controls permutation code mechanism which opens the circuit of a magnet to arrest the distributer for a time determined by a screw-and-follower when the tabulating signal is transmitted after a "shift" code signal but not when the same code signal (which then represents a character) is transmitted after an "unshift" signal. Transmitter.-In the five-unit code transmitter described, the five tape-sensing levers 49, Fig. 2, controlling transmitter contacts 18, have arms 64 co-operating with five letters 73, pivoted at 74, controlling five code bars 81 adapted to select one of three selector members 84, 85, 86 when the code corresponding to the " shift," tabulating," and " unshift " signals is transmitted. When the member 85 is selected, it is moved to the right in Fig. 3 by a cam-operated bail 105, and thereby operates a lever 88 to withdraw a pin 108, Fig. 5, from the thread of screw 109, thereby allowing a spring 119 to move lever 107 to open contact 25, Figs. 1 and 5, in the circuit of magnet 22 which arrests the distributer arm in its stop position. When the pin 108 engages the screw, it is constantly urged to the right to hold contact 25 closed ; when it is withdrawn, it is moved by lever 107 to the other end of the screw with which it engages when the selector member 85 is restored, so that contact 25 remains open until the pin 108 reaches the right-hand end of the screw. The selector members 84, 86 serve to permit and prevent, respectively, the operation of the member 85 for the reason stated above (Figs. 6, 7, 8, not shown). Receiver.-The receiver is described in U.S.A. Specifications 1,904,164 and 2,076,864 and comprises a slotted tabulator bar 32 having adjustable stop members 37 co-operating with a cam striker 38 carried by the type-carriage 29 to determine the continuous movement of the carriage to the next tabulating position. The " tabulating " signal selects the function lever 42 controlling this movement.

Title: Improvements in and relating to means for coating hot elements with powdered materials
IPC: B21C23/32
Filed: 1964-03-26
Abstract: 1,049,077. Coating apparatus. COMPAGNIE DU FILAGE DES METAUX ET DES JOINTS CURTY (CEFILAC). March 26, 1964 [March 29, 1963], No. 12959/64. Heading B2B. Hot billets 15 are coated with a lubricating powder while supported on a conveyer 1, the conveyer being adapted to form a deep pocket 11 at one location of its run to hold and rotate the billet while powder is dispensed on it by a dispenser 13. Formation of the pocket may be achieved by diffe - rentially varying the speeds of two of the rollers 2, 4 supporting the chain conveyer so that slack in the chain is accumulated at the given point beneath the dispenser. Alternatively guide rollers or rails (Figs. 3, 4 not shown) which bear laterally upon the conveyer or on supporting wheels thereof may be used to depress the chain into the form of a pocket. Removal of the billet from the pocket may be achieved by straightening the conveyer again, as shown at 12, the billet then being conveyed forwardly to a suitable receptacle 14 in preparation for further operations such as extrusion or piercing. Alternatively the roller at the outlet side of the pocked may be lowered allowing the billet to move out of the pocket (Fig. 2 not shown) or the billet may be ejected in a direction transverse to the run of the conveyer by a push-rod device (Fig. 4 not shown).

Abstract: 799,235. Cutting-out presses. BOBST & FILS SOC. ANON., J. April 27, 1956 [April 16, 1956], No. 13005/56. Class 31 (1). [Also in Groups XVI and XXX] In a press for cutting out material in the form of sheets which are conveyed by means of gripper bars 5 carried by a pair of intermittently-movable endless chains 4 which pass around a pair of wheels 7 whose shaft is keyed in movable blocks 10 which are subjected to an action to tension springs 11, means are provided for varying the tension applied to the conveyer chains in synchronism with the operations of the press so that the tension is less during the periods when the chains are stopped than between such periods. The chains are stopped periodically by mechanism which causes the gripper bars to bear against stops 8, 9. As shown in Fig. 2, the means for periodically varying the tension of the conveyer chains comprises a pair of compression springs 16 which act on the blocks 10, movable in slideways 13, through the intermediary of non- rotatable straps 15. Each spring 16 surrounds a rod 17 of an eccentric 18 and is held under tension between fixed and adjustable washers 20, 20<SP>1</SP>. The rod 17 has a head 22 slidable in a recess in the strap 15. When the spring 16 is inactive, as shown, there is a small clearance 23 between the washer 20<SP>1</SP> and the strap 15 so that during one complete rotation of the eccentric 18, the shaft 19 of which is connected to the main shaft of the press, there is an inoperative period during which the spring 16, although displaced, has no effect on the strap 15 and an operative period during which the spring 16 bears against the strap 15. The springs 16 may alternatively act in the plane in the arrow 14. The eccentrics may be replaced by levers or cams and tension springs may be used instead of compression springs. Further, instead of providing auxiliary springs 16, the tension of the springs may be modified periodically, e.g. by hydraulic means.
